There is an RV onsite hooked to an existing gravity septic system with some original septic records from 1969. There is an existing 1,000-gallon septic tank followed by a gravity drainfield. This septic is not in failure but is located where the new manufactured home is proposed and is old so the owner would like to upgrade it along with putting in the new house. The old tank is to be decommissioned or removed. The old drainfield is m be abandoned. Proposed is compliant repair/replacement septic with a new 1,000-gallon operating capacity minimum 2- compartment septic tank with an effluent filter followed by a new I,000-gallon pump chamber. The new tanks are over 50 feet to the shoreline. The new drainfield consists of 300 s.f of shallow pressure bed using an application rate of 0.8.The system will also have a control panel including timed dosing,a counter and elapse meter to prevent overuse and facilitate ongoing operation and maintenance. This is a compliant repair with 24"+vertical separation. There are no known wells within 100 feet. The drainfield meets 100'+ setback to the shoreline and we have also designated a full reserve drainfield area. The property owner's contact information is as follows: Steve Fors PO Box 3287 Belfair, WA 98528 (253) 225-0813 If you need further information, please contact my office at(360) 898-2255.

Install bed bottom level. ' 3. Install locator tape or rebar at each end of all drainfield laterals. 4. Install observation ports as indicated on the plot plan. Minimum of 2 required in each bed with bottom extending to the draimock/native soil interface. Glue"T" to bottom so Observation Port cannot be easily removed from ground. Install removable cap on top of port at final grade level. 5. Install drainfield during dry weather and soil conditions; any soil smearing must be eliminated by hand raking. 6. Install threaded clean-outs at the end of all laterals (cap must extend to within six inches of finished grade and be marked with locator tape or rebar). 7. Install audio/visual high water level alarm. Redundant off switch required. 8. Install 1/8"mesh non-corrosive pump screen (min. 12 sq. ft. surface area, not to interfere with controls or floats.) Or pump screen may be substituted with Bio-Tube in septic tank and block under pump. Pull bio-tube every 6-12 months and flush back into tank. 9. Install check valve in pump outlet line to prevent system from draining back into the pump chamber. 10.Tee to Tee construction between laterals and manifold with orifices oriented at 6 o'clock. Install laterals to the manifold with the orifices at 12 o'clock, (do not glue), after pressure test and Environmental Health Dept. approval, turn orifices down (6 o clock) and glue laterals to manifold. Orifice shields may be used with orifices in the 12 o'clock position in lieu of turning the orifices down to the 6 o'clock position. 11. Filter fabric required over drain rock prior to back filling. If the drain rock extends above natural grade, tun the filter fabric at Least 2 inches down the trench wall. 12. Encase all water lines within 10' of drainfield and under any driveway/parking areas. 13. Divert all storm water runoff away from on-site sewage system. 14. No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the drainfield and reserve area. 15. Have the septic tank and pump chamber pumped or inspected every 3 years minimum. 16. No vehicular traffic over drainfield area. 1 Z Inspect floats, clean filters, and test high water level alarm every 6-12 months as needed. 18. All materials and workmanship must meet County and State regulations. 19. Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 20. All manhole lids and access, sampling or inspection ports must have locking covers and be located at ground Level. 21. All pressure systems with a pump chamber outlet higher than the drainfield must have an anti-siphon valve or a 1/8" hole drilled in the discharge pipe above the pump to prevent siphoning. Ensure anti-siphon hole sprays down/away from tank opening. 22. All transport lines under driveways or parking areas must be encased to prevent crushing. 23. Homeowner is responsible for all property lines and easements. APPROVED JUN 26 2024 NASOS �cSk?' E!�PET YE4%L HEALTH ��
